Fetch an indication of whether the interface supports capturing in

monitor mode at the same time that we fetch its list of link-layer
types.  Support fetching that list in monitor mode, as the list may be
different in regular and monitor mode.  If the interface supports
monitor mode, when printing the list of link-layer types, indicate
whether they're fetched in monitor mode or not, as tcpdump 4.1.x does.
